RUNBIG(C)                XENIX System V                 RUNBIG(C)



     Name
          runbig - Runs a command that may require more memory than
          normal.

     Syntax
          runbig command [ arguments ]

     Description
          runbig executes commands that may require more memory than
          is normally available to a user process.  While runbig is
          executing the specified command, it ignores the restriction
          on the default of memory available to the user process.  The
          command will run normally until it grows to be larger than
          the amount of memory available to a user process.  It is
          then locked in core memory and not swapped until it either
          exits or shrinks to a size less than or equal to the size of
          a default user process.

          The removal of the process size restriction during execution
          of runbig will be preserved during an exec(S) system call,
          but not for a fork(S) system call.

     Notes
          Running programs greater than the default process size, and
          therefore, possibly greater than the size of the disk swap
          area, may severely impact system performance.

          runbig has no effect on systems whose memory size is much
          less than the size of the disk swap area.
